Embodiment of the present invention provides a kind of multi-connection processing method and device of network application.Can be when searching polynary group of table of prediction connection, obtained the information of extraction in first connection simultaneously, when the packet that the next one is connected is handled, just a plurality of connections that belong to a kind of network application can be associated together like this, realize respectively connecting sharing of institute's information extraction; Provide the next forwarding that connects packet to handle owing to set up polynary group of table of prediction connection simultaneously, so when the data of a plurality of connections being transmitted processing, with regard to not needing each bar is connected the process of all carrying out agreement identification, saved Internet resources, improved the efficient of system's operation.
For better describing embodiment of the present invention, now in conjunction with the accompanying drawings the specific embodiment of the present invention is described, be illustrated in figure 1 as the schematic flow sheet of the described method of embodiment of the present invention, described method comprises:
Step 11: the address four-tuple of obtaining the next both sides of connection.
Specifically, be exactly in multi-link network application, if an end of having set up in the two ends that connect needs to connect with the other end again, then from the negotiation data bag of this first connection, obtain IP address and port address four-tuple that the next both sides of connection will use.
Here be sake of clarity, can be set at client C1 and server end S with having set up the two ends that connect, when C1 needs to connect with another client C2 again, C1 can send a negotiation data bag to S, this moment is by obtaining this negotiation data bag and this packet being resolved, in the time of just can obtaining next the connection, IP address and port address that C1 will use are right; Then S again with C2 mutual after, return to a response of C1 negotiation data bag, this moment is by obtaining this response negotiation data bag and this packet being resolved, in the time of just can obtaining next the connection, IP address and port address that C2 will use are right, have so just got access to IP address and port address four-tuple that next connection both sides C1 and C2 will use.Because in actual networking, the address of C1 and C2 may be moved at any time, so IP address that C1 and C2 provided and port address are to being one or more pairs of, IP address that is obtained so and port address four-tuple are exactly the ordered series of numbers that comprises one or more pairs of addresses.
Step 12: set up prediction and connect polynary group of table.
Specifically, exactly after the operation of carrying out step 11, just can be from the IP address and port address four-tuple ordered series of numbers that are obtained, set up polynary group of table of prediction connection for two or three that choose correspondence.
If set up prediction and connect polynary group of table for two that choose correspondence, then all the IP addresses of an end or all the IP addresses or the port address of the port address and the other end are made up respectively, set up the prediction that comprises two tuples and connect polynary group of table.
For instance, if the IP of the C1 that obtains and port address are to being IP1 and port one, and IP2 and port 2; IP that corresponding C2 obtained and port address are to for IP3 and port 3, and IP4 and port 4.So just can in IP1 and port one, choose one, in the IP3 of correspondence and port 3, choose one, it be made up in twos form the list item that prediction connects polynary group of table; Or in IP2 and port 2, choose one, and in the IP4 of correspondence and port 4, choose one, it is made up in twos form the list item that prediction connects polynary group of table.The rest may be inferred, when the IP that obtains and port address are a plurality of to having, as long as choose corresponding IP or port address, just it can be made up and form the list item that prediction connects polynary group of table.
In the practical operation, because two that choose correspondence are made up the prediction of being set up and connect polynary group of table, its forecasting accuracy may be not high, so set up polynary group of table of prediction connection for three that also can choose wherein, be exactly specifically, all IP addresses of one end and port address pair are made up respectively with all IP addresses of the other end, set up the prediction that comprises tlv triple and connect polynary group of table; Or all IP addresses of an end and port address pair made up respectively with all of the port address of the other end, set up the prediction that comprises tlv triple and connect polynary group of table.
For instance, if the IP of the C1 that obtains and port address are to being IP1 and port one, and IP2 and port 2; IP that corresponding C2 obtained and port address are to for IP3 and port 3, and IP4 and port 4.So just can choose IP1 and port one and corresponding IP3 or port 3 and make up, form the list item that the prediction that comprises tlv triple connects polynary group of table; Also can choose IP2 and port 2 and corresponding IP4 or port 4 and make up, form the list item that the prediction that comprises tlv triple connects polynary group of table.The prediction of Jian Liing connects polynary group of table like this, owing to comprised three addresses that connect both sides, so accuracy for predicting is higher, has effectively improved the efficient of system's operation.
Step 13: shared the importing into of link information predicted in polynary group of table of connection.
Specifically, exactly after having set up polynary group of table of prediction connection, just the last time can be connected, the information of being extracted in just connecting is for the first time imported described prediction into and is connected in the polynary group of table, the information of being extracted in connecting for the first time described here can be distinctive information such as the account number, password of the communicating pair that connects for the first time, like this when being connected to next time, just can connect polynary group of table by searching prediction, the information of being extracted in obtaining to connect last time, the multi-link association that realizes information is with shared.
